I'm all for using as few buttons as possible. Opera does this very well, especially with their 'paste and go' function. It lets you copy a URL, and then with a right mouse click you can paste-and-go it in your address bar and the URL opens immidately. This saves you from pressing the enter button or a 'go' button in your browser. Could something like this be implemented in OmniWeb? It's really usefull :)
